uterine cramps when pregnant

I'm 22 weeks preggo, FTM... I'm having nearly daily uterine cramps, like my entire uterus is tightening up and contracted. Feels like a bad period cramp but fleeting, about 10 seconds long and then the tightness of my uterus slowly subsides.... helps to make it stop when I move... I'm thinking Braxton hicks? 
Anything I need to look outt for?  No bleeding, no spotting, I am feeling baby move every day...
